The largest mound of the Bremore Passage Tombs measures approximately 30 metres in diameter, and survives to a height of about 3.5 metres. The off-centre hollow in the mound is what remains of its collapsed burial chamber and there are suggestions of a passage running from here to the north-west.
Less clear is the presence of four other, much smaller mounds. There are two to the south-west, 9 metres and 15 metres in diameter respectively. Another, 12 metres in diameter, lies to the south east, with a fourth, about 11.5 metres in diameter, to the south-east of that. These smaller mounds have been badly affected by many, many generations of agricultural activity here and are all now no more than 1 metre high.
The roughly linear arrangement of the smaller tombs either side of a main tomb is similar to that found around Cairn L and Cairn T at the hilltop passage tomb cemetery of Loughcrew in Meath. The Bremore Passage Tombs also share a similarly prominent location in the landscape, as well as the possibility that the main tomb has a solar alignment. In this case, from what can be roughly deduced from the visible elements of the possible passageway, it may have been aligned with the summer solstice sunset.
What is really interesting about this small passage tomb cemetery is its location. For today’s visitor who has walked some distance to find it, Bremore is a quiet spot, well off the beaten track, where you can enjoy the peaceful sounds of the wind and the waves and seabirds. It would not be unusual to have the place to yourself. Research in the headland and the fields to the west of it tells us that this was not the case in the Neolithic. This coastal land was not just a place of burial, but also a place of activity and everyday life. Evidence has shown that it was the location of extensive stone tool production, mainly using nodules of flint that could be found on the beach. This and other activities were focused in particular around the tombs. The people living here were not alone on this piece of coastline either as another small passage tomb cemetery has been recorded at Gormonstown, just 1.5km to the north. These two cemeteries were inter-visible but perhaps belonged to two distinct communities as the mouth of the River Delvin, which even today forms the boundary between Fingal and county Meath, runs between them. As we can see from other places such as the Lingaun Valley, sometimes these modern county boundaries have truly ancient origins!
